Definitions

  • the present invention relates to a valve for a liquid system of the type mentioned in the preamble of claim 1 and a liquid system of a vehicle.
  • valves for liquid systems and liquid systems for vehicles are already known from the prior art in numerous design variants.
  • the known valves for fluid systems in vehicles include a valve housing with a plurality of valve housing openings, a valve body which is arranged in the valve housing so as to be rotatable about an axis of rotation and has at least one flow-conducting connection channel for the flow-conducting connection of at least two valve housing openings of the plurality of valve housing openings, one between the valve housing and the Valve seal arranged on the valve body with valve seal openings corresponding to the valve housing openings, a valve drive for automatic rotation of the valve body about the axis of rotation and a plurality of connection pieces corresponding to the valve housing openings for flow-conducting connection of the valve to the rest of the liquid system.
  • the relevant connecting pieces known from the prior art usually have a circular inner contour and a circular outer contour in cross section.
  • the object of the present invention is to improve a valve for a liquid system and a liquid system of a vehicle.
  • the vehicle can be, for example, a land vehicle designed as a motor vehicle. Motor vehicles embodied as an electric vehicle or as a so-called hybrid vehicle may be mentioned here purely by way of example. However, the invention can also be advantageously used in other land vehicles as well as in air and sea vehicles.
  • the valve according to the invention can preferably be a so-called multi-way valve. However, this is not necessarily the case.
  • the dependent claims relate to advantageous developments of the invention.
  • An essential advantage of the invention lies in the fact that a valve for a liquid system and a liquid system of a vehicle are improved.
  • the aforementioned valve and the aforementioned liquid system can be implemented in a particularly simple manner in terms of design and production.
  • the invention makes it possible for more complex liquid systems with, for example, more complex valves, such as multi-way valves, and with further components of these liquid systems connected in a flow-conducting manner to these valves, to be implemented relatively easily in comparison to the prior art.
  • the invention enables extensive centralization of the assemblies of liquid systems, such as liquid tanks, pumps and the aforementioned valves. In this way, for example, housing parts for a plurality of assemblies of a liquid system, for example the aforementioned assemblies, can be used at the same time.
  • the individual assemblies of a liquid system must be connected to one another in a flow-conducting manner by means of additional hoses or the like.
  • at least one of the plurality of connecting pieces can optionally be directly connected in a flow-conducting manner to a hose or a pump. Accordingly, the flexibility of the valve and the liquid system equipped with it is significantly increased.
  • the wording "can be directly connected in a flow-conducting manner" means that either the hose or the pump can be connected directly to this connection piece of the valve. For example, it is therefore not necessary for the aforementioned pump to be connected to the connecting piece in a flow-conducting manner by means of an additional hose.
  • valve according to the invention can be freely selected within wide suitable limits in terms of type, function, material and dimensioning.
  • valve according to the invention provides that a cross section of a free end of this connecting piece is arranged transversely to the corresponding valve housing opening, preferably perpendicularly to the axis of rotation.
  • this connecting piece is further improved in terms of design and production technology.
  • this enables a very compact and therefore space-saving design of the valve and of the liquid system equipped with it.
  • valve according to the invention provides that this connecting piece is designed in such a way that a plurality of the valve housing openings, preferably a plurality of valve housing openings arranged one above the other along the axis of rotation, can be connected in a flow-conducting manner to the hose or the pump by means of this connecting piece. This further improves the compactness of the valve and the liquid system equipped with it. This applies in particular to the preferred embodiment of this development.
  • valve according to the invention provides that this connecting piece is designed as an integral part of the valve housing, preferably that this connecting piece is molded directly onto the valve housing. In this way, the number of components and thus the structural complexity of the valve and the liquid system equipped with it can be reduced. This can be implemented in a particularly simple manner in terms of design and production by means of the preferred embodiment of this development.
  • valve according to the invention provides that a free end of this connecting piece is designed as a valve-side coupling part of a coupling for selectively coupling the valve directly to the hose or the pump, preferably as a valve-side quick coupling part of a quick coupling.
  • a free end of this connecting piece is designed as a valve-side coupling part of a coupling for selectively coupling the valve directly to the hose or the pump, preferably as a valve-side quick coupling part of a quick coupling.
  • an advantageous development of the liquid system according to the invention according to claim 9 provides that on the one hand a free end of this connecting piece is designed as a valve-side coupling part of a coupling for selectively coupling the valve directly to the hose or the pump, preferably as a valve-side quick coupling part of a quick coupling, and on the other hand, the hose and the pump each have a coupling part corresponding to the valve-side coupling part, preferably a quick-coupling part corresponding to the valve-side quick-coupling part.
  • this connecting piece has a circular flow passage area in cross section at a free end and the valve housing opening corresponding to this connecting piece has an essentially rectangular cross section, the valve housing opening being larger than the flow passage area at the free end of this connecting piece , and the flow passage area of this connecting piece widens in the manner of a diffuser from its free end to the corresponding valve housing opening and gradually merges into the valve housing opening.
  • this connecting piece makes it possible for the connecting pieces and the valve housing openings corresponding thereto to also have cross sections with non-circular inner contours, in contrast to the prior art.
  • the cross sections with essentially rectangular inner contours have a clear width that is larger than that of a cross section with a circular inner contour. According to the invention, it is thus possible to make particularly good use of the available installation space for the valve housing openings in the valve housing.
  • the installation space for the valve housing openings in the valve housing is very limited on the circumference, ie concentrically around the axis of rotation of the valve body. Accordingly, circular valve housing openings, for example, can only be enlarged to a limited extent in order to optimize the flow through the respective valve housing opening and the connection piece corresponding thereto.
  • valve housing is designed as an integral part of a liquid tank of the liquid system, preferably a coolant tank of the vehicle for storing coolant carried in the liquid system designed as a coolant system.
  • a coolant tank of the vehicle for storing coolant carried in the liquid system designed as a coolant system.
  • the liquid system according to the invention can also be freely selected in terms of type, function, material and dimensioning within wide, suitable limits.
  • the vehicle is designed here as a motor vehicle, specifically a purely electric vehicle, and is not shown in any more detail.
  • the liquid system 2 for the vehicle is designed as a coolant system for cooling the drive battery, the drive motor together with the corresponding power electronics and for cooling a refrigerant circuit for air conditioning an interior of the vehicle.

  • the liquid circuits are also not shown.
  • the valve 6 is designed here as a so-called multi-way valve and comprises a valve housing 8 with a plurality of valve housing openings, a valve body which is arranged in the valve housing 8 so that it can rotate about an axis of rotation 10 and has at least one flow-conducting connection channel for the flow-conducting connection of at least two valve housing openings of the plurality of valve housing openings, a valve seal arranged between the valve housing 8 and the valve body with valve seal openings corresponding to the valve housing openings, a valve drive for the automatic rotation of the valve body about the axis of rotation 10 and a plurality of connecting pieces corresponding to the valve housing openings for the flow-conducting connection of the valve 6, namely the valve housing openings, with the remainder of the liquid system 2.

  • the valve housing 8 is in the form of a plastic injection-molded part, onto which the connecting pieces, for example the connecting piece 12 , which are also in the form of plastic injection-moulding parts, are injection-moulded.
  • the injection seam 13 is in the Figures 1 to 3 clearly.
  • the connecting piece 12 is thus designed as an integral part of the valve housing 8 .
  • slides can be used, in particular during the production of the valve housing 8 .
  • other connection techniques are also conceivable.
  • the person skilled in the art will select the appropriate connection technology for the connection. Purely as an example, only plastic welding, gluing techniques and screw connections are mentioned as alternative connection techniques.
  • connection piece 12 is designed and arranged in such a way that a hose (not shown) or a pump 14 of the liquid system 2 can be connected directly to the valve 6 in a flow-conducting manner by means of this connection piece 12. See the 2 and 3 .
  • this connection piece 12 the free end of this connection piece 12 as a valve-side coupling part 16 of a coupling 18 for selectively coupling the valve 6 directly to the aforementioned hose or the pump 14, namely as a valve-side quick coupling part of a quick coupling.
  • the liquid system 2 in the present exemplary embodiment also has at least the aforementioned hose and at least the pump 14, with the connecting piece 12 of the valve 6 on the one hand and the hose and the pump 14 on the other hand being designed and arranged in such a way that either the hose or the pump 14 can be connected to this connecting piece 12 directly in a flow-conducting manner.

  • the connecting piece 12 is designed here in such a way that by means of this connecting piece 12 a plurality of valve housing openings, namely the valve housing openings A and C arranged one above the other along the axis of rotation 10, can be connected in a flow-conducting manner to the aforementioned hose or the pump 14.
